# Ex skeletal makefile for version 7
#
# NB: This makefile doesn't indicate any dependencies on header files.
#
# Compiles in both the LISP code and (the undocumented) chdir
# command within the editor; take these out of CFLAGS to make some
# breathing room in the text space if necessary.  If you take out -DLISP
# you should move ex_vars.nolisp to ex_vars.h
#
# If your system expands tabs to 4 spaces you should -DTABS=4 below
#
# Ex is likely to overflow the symbol table in your C compiler, so
# it uses -t0 which is (purportedly) a C compiler with a larger
# symbol table.  The -t1 flag to the C compiler is for a C compiler
# which puts switch code in I space, increasing the text space size
# to the benefit of per-user data space.  If you don't have this it
# doesn't matter much.
#
# Ex wants stdio only to get the doprnt.o routine; if other stdio stuff
# gets dragged in that is a mistake.
